arc3d is incomplete when n is missing #369

Hello,

When we don't set n in arc3d, the arc does not join the two points:

library(rgl)

A <- c(0, 0, 1)
B <- c(0, 1, 0)

arc3d(A, B, c(0, 0, 0), 1, lwd = 3)

points3d(rbind(A, B), size = 12)

rgl Version: 1.1.15
R Version: 4.3.0
Platform: Linux Mint 20

I believe this is fixed in #374. Thanks for the report!
